Application filed February 5, 1908. Serial Ncf 414,322.-

' the said means being breakable from the ex- 4 terior of said body to release said shackle.

The breakage of the securing means indicates .that the seal has been tampered with, and

v the shackle wirecannot be re-secured with out inserting a new and unbroken device.

In the accompanying drawing-Figure 1 is a'face view of my improved seal fastening.

Fig. 2 is a section on the line 2. 2. of Fig. 3.

. Fig. 3 is a section on the line 3. 3 of Fig. l,

showing the breakable block, in place and mode of breaking said block. Fig. 4 is a similar section showing the block broken and the shackle wire beingremoved. Fig. 5

shows the shackle wire, and Fig. 6, the break-v ableblock separately.

Similar letters of reference indicate like turned over the flange B. The case and cover here together form a seal body. Centrally disposed in the case'A is a rectangular opening E which receives a similarly formed projection F on the back of the block G, said projection and block forming a breakable lock which may be made of cla porcelain,

' a glass or any frangible materia. The projection F is undercut to form a recess H. The block is inserted in the o ening E so that, as shown in Fig. 2, one ang e of the projection F comes directly in front of and bears upon the internal case projection O. The shackle wire I has its end portions J bent upwardly in V form and the length of said end portions is such that when the wire is in place, as shown in Fig. 2, the extremities of said end portions enter the undercut recess H and abut on the solid portion of projection F extremities and the internal case projec= tion C.

In assembling the device, the projection-F of the breakable block is inserted in theopening E. The turned up portions J of the" shackle wire I, are then passed through the entrances in the wall of case A, meeting the inclined upper surfaces of projection F and being sprung asunder therelry, until the upper extremities of said turned up portions slip into the recess H and take an abutment against the solid part of said projection.

The shackle wire cannot be withdrawn from the case A, without breaking the seal. This may be done by inserting any wedge shaped instrument. (dotted lines Fig. 3) under the edge of block G and rying outwardly. The seal will then be bro on and easily detached as shown in Fig. 4, the smaller portion 'K dropping within the case and being removable through the opening E. The shackle wire may then be withdrawn. Whenever it is desired to re-secure the wire, a new breakable block is inserted in the case, in the manner already described. v

I claim? 1. In a seal fastening and in combination with a shackle Wire in loop form, a seal body and means within said seal body Wherewith each leg of said shackle independently engages: the said means being breakable from the exterior of said body'- to releasesaid shackle. l

2. Ina seal fastening and incombination with a shackle wire in 100 form having its end portions turned upwar a seal body and means within said body on aging with said turned up ends and breaka is from the exturned up ends and breaka lefrom the ex- 100 terior of said body to release said shackle: the bends in said shackle formed by turning up said end portions being in contact wit the inner surface of said body.

4. In a seal fastening and in combination 105 with a shackle wire having its end portions turned upward, a seal body and in said body, a block of frangible material extending through awvall of said, body and having on its under sideand within said body, a recess 110 so that said solid portion lies between said receiving said turned u ends of said shackle Frire and forming a 100 'ng abutment there- 5. ha seal fastening, and, in combination with a shackle. wire having its end portions turned upward, a hollow seal body, a fixed projection extending inward from a circumferential wall of said body and a block of frangible material extending through a face wall of said body and in contact with said projection; the said block having, on its under side and within said body, a recess receiving said turned up ends of said shackle wire and forming a locking abutment therefor.

6. In a seal fastening and in combination with a shackle wire having its end portions turned upward, a hollow seal body of metal,

a projection integral with said body extending inward from a circumferential wall of said body and a block of frangible material of po- 20 lygonal cross section extending through a correspondingly formed opening in a face wall of said body and in contact at one of its angles with said projection; the said blocl having, on its under side, and within said seal 25 body, a recess receiving said turned up ends of said shackle wire and forming a locking abutment therefor.

In testimony whereof I have aflixed my signature in presence of two witnesses.
